create a hex_dump_to_buffer_ext with a new argument
and a new static inline for the old hex_dump_to_buffer
without modifying the argument list that calls
hex_dump_to_buffer with whatever added argument content
you need.
Something like:
static inline
int hex_dump_to_buffer(const void *buf, size_t len, int rowsize,
int groupsize, char *linebuf, size_t linebuflen,
bool ascii)
{
return hex_dump_to_buffer_ext(buf, len, rowsize, groupsize,
linebuf, linebuflen, ascii, 0);
}
and remove EXPORT_SYMBOL(hex_dump_to_buffer)
